funny thing is DQ8 has one of the smallest worlds in a DQ game (except DQ1 or 2 maybe)
i was quite disapointed, i played DQ8 after 1-7,9, and 11, and said "what that's it?"
Dragon quest 7 is TOO MASSIVE like 100 hours on Switch (to absolute 100%, on hardest difficulty settings), thats SUPER easier and shorter than PS1 game which is around 200 hours to complete 100%, 3ds version was slightly faster an still was like 150 hours for me,
there's so many areas in present AND Past time, so much story, so much... period!
to be fair it's about TOO big, most people drop it from burning out
Dragon quest 3 has you go through the DQ1 and 2 world map for the 2nd half of the game, even the easier remake 2DHD took me 70 hours to 100% it all on normal difficulty
